Re: Wheel direct drive
I'll echo Don's comments about ratios; one of the reasons we're using chain in our setup is so that we have a fallback in case we completely misread the way the game would be played. Since we're Week 3 this year, we have a clue as to which way the game will be played. If we need to adjust our drive system, we just need to order some new sprockets, switch them out on Thursday at Chesapeake, and we're golden.
The other advantage to chain is that chain is an easy-to-fix place to have a drivetrain fail. Ideally you would have zero failures, but I'd much rather throw a chain than bend a shaft or otherwise bust a part.
